IMPROVEMENT Ill PLQUGH-ULEVIS.

Be it known that I, RQGER SANDIFORD, of the city of Joliet, in Will county, and State of Illinois, have invented a, new and useful Imnrovement on a'Plough-(llevis; and that I do hereby declare the following to be it full, clear, and exact description of the same, reference being had to the annexed drawings, making a. part; of thisspecificetion, in Which-- Figure l is a plane view on thetop,

Figure 2, a sideelcvation, and

Figure 3 n side elevation of a part of said invention.

The nature of my invention consists in the construction and. arrangement ofe plough-elevis, by which it is nmde ensy to at onceregulnte-the depth to he cut, and guide the plough to either side.

a, fig. 1, is a view of '2. double segmental olcvis, secured to the plough-beam b by means of the regulatingholtsc and d, as in the ordinary manner. In conjunction with the clevis Q1 use the transverse oscillatingclevis e, regulated at any joint, up or down, by means of the regulating-boll: 2' passing through the double row of holes in the segmental olevis a, more particularly shown in fig. 2. It will be seen that by elevating 0r lowering the outer end of the clevis 2, any depth may he'obtuined, and by regulating the draught-line, by means of the row of holes in said clevis, any width of furrow may be out, consistent with the size of the clevis and plough. The clevis e is intended to be reversible, so as to give. greater facilities for'changing the lateral direction of the plough, and may be used in conjunction with the commonclevis. The elevis, a, is double, for the purpose of preventingthe other clevis from becoming twisted or getting out of shape, and may be used without the clevis c, as shown in fig. 3, When used alone, the double-tree may be attached to either of the projecting segments, or between them, as is desired.

Having thus described my invention, what I claim as new in my invention, and desire to secure by Letters Patent, is as follows: i

' 1. I claim the double segmental clevis a, when constructed, operating, and arranged substantially as and for the purposes set forth.

2, I claim the transverse oscillating-clevis 0, when constructed and arranged as and for the purposes described.

3 I claim the combination and arrangement of the segmental clevis a and transverse oscillnting-clcvis e, when arranged, constructedyand operating as and for the purposes setforth.
